! WARNING Read and understand, the installation, operating, and maintenance instructions thoroughly before installing or servicing this equipment. Only trained, qualified gas installation and service personnel may install or service this equipment.
! CAUTION This heater cannot be used in a building with an uninsulated roof or condensation problems can occur.
Design
To ensure a safe, properly designed heating system, a layout should be developed for the correct placement of the infrared heater(s). Aside from safety factors such as clearance to combustibles (see Chart 1.1 on page 5), you should take also into consideration the environment (e.g., cold/drafty, average, protected), heat coverage (sq. ft.) needed, heater centers, the distance behind a person or work station(s) and exhaust path. Also, the effective infrared surface temperature of a person or object may be diminished with wind above 5 mph. Wind barrier(s) may be required. Most importantly, clearance to combustibles must always be maintained! Refer to hazards on page 4.
This installation manual, along with national, state, provincial, and local codes, address these issues. It is critical that you read, understand, and follow all guidelines and instructions. Always inspect and evaluate the mounting conditions, space for exhaust, gas supply and wiring.
Perimeter mounting of infrared heaters provides the most effective distribution of heat. The recommended spacing between the heaters is shown in Chart 2.1. Add additional heaters in the center of the space when heaters are spaced farther than the recommended distance (see Figure 2.1 ).
When heated, materials high in hydrocarbons (solvents, paint thinner, mineral spirits, formaldehydes, etc.) can evaporate. This may result in odors or fumes being emitted into the environment. To correct this problem, clean the area and/or introduce additional ventilation. Heaters installed and serviced in accordance with the installation manual do not emit foul odors into the environment.
IMPORTANT: Fire sprinkler heads must be located at an appropriate distance from the heater. This distance may exceed the published clearance to combustibles. Certain applications will require the use of high temperature sprinkler heads or relocation of the heaters.
Sprinkler systems containing propylene glycol or other flammable substances are not to be used in conjunction with this heater without careful consideration for, and avoidance of, potential fire or explosion hazards. For further information, consult NFPA 13. Always observe applicable state and local codes.

Ventilation
! WARNING Insufficient ventilation may result in health problems, carbon monoxide poisoning, or death. Vent enclosed spaces and buildings according to national, state, provincial, and local codes. Improper venting may result in asphyxiation, fire, explosion, injury, or death.
It is required that the levels where heaters are mounted be properly ventilated to supply combustion air to the heaters and to sufficiently dilute the products of combustion. It is also required that the flue discharge area is kept clear of gas piping and electrical wiring (see Figure 2.4). This infrared heater must be vented in accordance with national, state, provincial, and local codes and the guidelines in this manual. In the United Sates refer to the latest edition of ANSI Z223.1 (NFPA 54) and in Canada refer to the latest edition of the CAN/CGA B149.1 & B149.2 Standard.

20˚ - 35˚
SIDE VIEW Provisions must also be made to provide sufficient fresh air intake area and exhaust air outlet area. For proper ventilation, a positive air displacement of 4 CFM/1,000 BTU/h of gas consumed mus be provided. Where insufficient air movement exists, induced air displacement is required. A balanced system is essential to avoid negative building pressure which causes excessive infiltration, unfavorable drafts, and affects combustion efficiency. Air displacement may be accomplished by either natural or mechanical means. Mechanical exhausters are preferred and typically mounted at high points on the roof where stagnant air accumulates inside the building. For a flat roof, considerations of prevailing winds, high and low pressure areas, and distribution of air movement must be taken into consideration when locating exhausters. Best air distribution is accomplished by using a number of small exhausters versus one large exhauster. Provide a minimum of one square inch of inlet area per 1,000 BTU/h for combustion air supply. Inlet opening in the building should be well distributed (see Figure 2.1) high in the sidewalls and should direct incoming air upward to dilute products of combustion while preventing drafts at lower levels. Inlets are typically 1 to 3 sq. ft. Local codes may require that mechanical exhaust systems be interlocked with heaters to enable both to function simultaneously (see page 17, Figure 2.6) or allow control of exhausters with a ceiling mounted humidistat.

The unit must be electrically grounded in accordance with local codes, or in their absence, with the latest edition of the National Electrical Code, ANSI / NFPA 70 and/or the Canadian Electrical Code CSA C22.1, latest edition. Control systems are initiated by either 120 VAC, 24 VAC or millivolt energy. The 120 VAC systems can be used directly from a 120 VAC line. On 24 VAC systems, transformers must be used to supply power of sufficient VA rating for single or multiple connected installations. Millivolt systems require NO external power, as energy needed to operate the valve is developed by the power-pile generator. Do not use multiple connections, as one thermostat may only control one heater. For wiring of controls on the unit, see the Figure 2.6 below. It is recommended that the thermostat be installed on the hot side of a fused supply line and have sufficient ampere capacity rating for the heater(s) it will control. The ventilation system may not be controlled separately from the heating system (consult local codes) by the use of a humidistat that closes then the humidity rises. The humidistat control should be installed at roof level. For summer ventilation, a simple on/off switch can be installed at the occupant level.

! WARNING Do not attempt to ignite a direct spark ignition heater by hand. Failure to comply could result in personal injury, property damage, explosion, fire, or death.
Upon satisfactory completion of the electrical supply and purging of the gas supply line to the heater(s), follow the lighting instructions on the heater’s rating label to put the heater into operation. Direct Spark Ignition Lighting Instructions 1 Rotate the heater’s valve knob to the “ON” position. 2 Close electrical circuit (typically the thermostat). 3 If the heater fails to light, turn off gas, open electrical circuit and wait 5 minutes before repeating the above steps. Shutdown Instructions 1 Open electrical circuit. 2 Rotate the heater’s valve knob to the “OFF” position. Sequence of Operation Starting Circuit: Upon a call for heat, voltage is applied to L1 and Neutral. After a pre-purge, the spark electrode is energized and the gas valve opens. The trial for ignition is 15 seconds. If flame is not sensed, the heater will attempt two more times to reignite. Running Circuit: After ignition, the sensing electrode monitors the burner flame. If sense of flame is lost, the control immediately acts to reignite the gas-air mixture. If flame sense is not established within 15 seconds, the heater will attempt two additional ignition sequences before proceeding to hard lockout. The control can be reset by briefly interrupting the power source. Millivolt Lighting Instructions 1 Purge main gas supply line. 2 Slightly depress and rotate the heater’s manual gas valve knob COUNTERCLOCKWISE from the “OFF” position to the “PILOT” position. 3 Fully depress the manual gas valve knob and light the pilot burner. Continue to depress for 30 seconds and then release. 4 Rotate the heater’s valve knob to the “ON” position. 5 Close the control circuit. If the heater fails to light, turn off the gas, open control circuit and wait 5 minutes before repeating the above steps. Shutdown Instructions 1 Open the control circuit. 2 Rotate the heater’s valve knob to the “PILOT” position, depress slightly and rotate to the “OFF” position. Sequence of Operation Starting Circuit: After manually lighting the pilot (see lighting instructions), upon a call for heat, the main burner solenoid is energized. The gas valve opens and the pilot lights the main burner. Running Circuit: After ignition, the powerpile monitors the pilot flame. If the pilot flame is lost, the powerpile cools and closes the valve within 180 seconds. See lighting instructions to relight the heater. 18 19 4.0 Maintenance • Maintenance Checks IHR Series Manual 4.0 Maintenance
It is recommended that the following become a standard yearly procedure to obtain maximum operating efficiency and trouble free operation.
During long periods of non-usage, remove or cover heater with a polyethylene bag and shut off gas supply. If further service to the heater is desired, contact your representative or the factory.
Main Burner 1 Gently use an air hose to blow any ! accumulated dust and/or dirt off the heater. WARNING Air hose pressure must not exceed 30 psig. Use protective glasses when cleaning the heater. 2 Gently pass the air hose over the entire exposed area of the ceramic. A distance of 2’ to 4’ from the unit is recommended.
